As shown in Figures l and 2 the rectangularframel is yformed with spaced and parallel upright end members 25 and 26secured to the `ends of horizontally `disposed spaced parallel top, 4intermediate and sill members 27,28l and 229 -respectively. The members 27 and 28 are suitably notched to receive `a pair Vofgvertically disposed `spaced inner and 4outer members'l and 32 which vertically divide the frame 20` to `provide it with the desired window opening 21 and a glass and `screiengsec- `tion vstorage .opening 21a adjacent to thel opening A21;.

As shown in the drawings the frame 20 :issprov'ided and A`36 being .,ofa length -to extend between :the tend' i the upper side/of -the sill 29 about midway between their,

members 2S and and being of a width to ,it between the members 31 ,-32, are alined insuperposedfrelatfionand secured to the lower side of the `memberxZS .and.-,to,

planar therewith'is secured to` the endfmember 25,1by.W several of the lscrews 3,8.v The Vtrack ,36 throughout-its,

length is .formed with spaced parallel inner `and [outer grooves l41 and 42 to 'slidably receive the Alower .edge p ortion of the glass sections 22 and 23 and `midway -be tween the Vgrooves 41 and 42 is formed with asimilar.

butV wider grooveV 43 ,toslidably receive the lloyver edge,`

portionio'f thescreen'-section24. YTo provide drainage Yfor opening `21 to provide'a.recessforapurposegtolrsehere` stops is entirely free.

the grooves 41, 42 and 43 the track 36 is provided with r a plurality of drainage holes 44 which communicate with the several grooves (Figures 2, 3 and 10). The strip 37 is formed with grooves 41a and 42a similar to yand alined with the grooves 41 and 42'to sealingly receive the vertical edge portion of the glass sections 22 -and 23 and with a groove 43a alined with the groove 43 to receive the vertical edge portion of the screen 24.

In order to provide a maximum of usable glass area i" against the outer edge of the frame and whose legs are slidably mounted in the screen frame and have their inner ends formed to limit its outward movement to the distance required to providenger space for the user.

A pair of locking means 60 each operable to lock one of the glass sections in its window opening sealing position andto unlock its glass section for movement to its v other position is best seen in Figures 5 and 6. These the Aassociated glass to sealingly seat therea'gainst and the interior side surfaces of the inverted channel-shaped track- 35 are iiat and coplanar with the flat sides of the grooves 41, 41a, 42 and 42a to allow the upper edge portions of the glass section to sealingly 'engage' lthereagainst. The opposite sides of the grooves 41, 41a, 42

and 42a are inclined in a mannerftending to force each 'glass into sealing engagement with the at side of its groove and the -coplanar hat surface of the track 35. 'Ihe track 35 is provided with a resilient.channel-shapedy strip l45 formed and arranged as shown in Figure 3 to "iii -resiliently engage and hold the glass sections'in their seal-v ing engagement. Still referring to Figure 3 it will be seen that the track 35 is also provided with another channel-shaped resilient strip 45 formed and arranged to resiliently engage the upper edge portion of the screen duplicates of and alined with the stops 46 and 47 in which case the inner edge of each stop would be slightly spaced from the surface of the adjacent glass section and could be provided with a suitable strip to seal the space, however it is presently preferred that the stops 51 and 52 be locking means are made the same to ysave the cost of providing diiierentlocks and each include a manually operable Z-shaped locking4 member'lll having a straight body portion 62 terminating in inner'and outer legs 63 and 64 bent to extend at 90 degrees to the axis vof the portion 62 and at an included angle of 13 5 degrees from each other. The4 body portion "62 is snugly journaled in a central loop portion 66 of a mounting bracket 65 to slightly resist rotation therein.

`Still referringlto Figures 5 and 6 the inner edge of the stop 51 midway between its-ends is formed to receive one of the locking members 61 and its bracket 65 which is secured thereto by wood screws 67. The other locking means .61 has its bracket reversed and secured upon the outer surfaceof the` outer edge of the screen frame by metal screws 68. With the bracket thus arranged -and the legs 63 in their unlockedaposition the lockingv `means do notinterfere with free movement of the glass and screen sections. Assuming that the glass and screen sections are positioned as shown in Figure 6 and the legs 63 and 64 of the locking `means are in their unlocked position, indicated by dot and dash line's in Figure 5, a 90 degree swinging movement of the outer legs 64`causes a like swinging movement of the inner legs 63 to their glass locking position across the rear edge of the glass so-that the glass sections are locked against'adventitious or surreptitious movement. The inner leg 63 is formed Awith a cam surface 69 formed and arranged'to gradually engage the inner edge of `the-associated glass in a manner to cause its outer edge to move into sealing engagement with the walls of the associated groove in the strip 38 by and during the locking movement.` A stop pin 63 is provided for each locking means'and is arranged to limit the locking movementof the outer leg to that l required. No 'stop is required for the unlocking'moveformed so that their inner edges sealingly engage the adjacent glass thereby preventing air and the elements glass sections are in their closed position (Figure 4).

from entering the space 21a or the building when the v50 in the event it becomes necessary to remove the glass I or screen sections, the stop 51is removed and the the opening 21. To replace, a section the foregoing procedure is reversed.

' As shown in Figure 8 the outer edgeof the glass sections are ush with the stops 51 and 52 when `not in use and the outer edge of the screen section' 24 is also ush with the stops 51 and 52 when not in use (Figure 7) so' that the window opening defined by the tracks Vand the In order to withdraw the Hush glass sections and move them to the position in which they close the opening 21, they are each provided with a clear plastic block 55 cemented to their inner lsurface adjacent their outer edge and each block is provided with` a nger piece 56 preferably in the form of a ringk pivotally anchored to its block. v l f l The outer edge vof the frame of thev screen section is then may be tilted and withdrawn from the track 35 and ment of the-lockingmeans since duringA this movement the leg 63 of the outer means swings against and is stoppedby theffs'creeniframe 24 andthe leg 63 of the inner means swings against and is stopped by the stop 51. The frictionaly engagement of the loop 66--with the portion 62 is such that the locking means is frictionally vheld in place. j 1

The frame 20 is adaptable to other wall constructions but has been shown as formed for installation'in building walls formed of 2 X 4 studs, to the outer side of which Sheathingsiding, shingles or similar materials and tothe inner side of which plastered or otherwise finished inner Walls are secured in the usual manner.

l Referring to Figures 4 and`8 it will 'be noted' that the overall dimension of the spaced members 31k and 32 is greater than the dimension of the end members 25 and 26 and that to provide nailing space for the sheathing .to the frame the member 32 has its outer surface adjacentto the opening 21arabbeted as shown in Figures 4 and 8, and

` to' allow the sheathing to extend over and close the space also provided with a linger piece 57 preferably in the Y between the members 27 and 28 has its top end formed as shown in Figure 2. The frame opening 21a, having its outer side covered by the sheathing and siding, does not show and since the opening 21 is trimmed by outer trim members in the usual manner the exterior appearance of my window simulates the appearance of conventional windows with the exception that the-opening of my window is not reduced in usable area by the unframed glass sections when they ,are closed. Theframe opening 21a also has its inner side vcovered by the inner Wall finishing material and my frame' is constructed to :allow assenso El this opening to be insulated in the same manner as the adjacent wall, if desired (Figures 4 and 8).

The inner side of the opening 21 is also trimmed by the usual trim members to simulate the appearance of a conventional window, however when it is desired to provide the window opening with a roller shade the top trim member is hinged as shown in Figure 3 to allow access to the recess 33 in which a roller shade 70 may be mounted in the usual manner. To guidingly receive and retain the sides of the shade and its free end reinforcing member 71, each side of the opening 21 is slotted as at 72 (Figures 3, 4 and 8).

When it is desired to provide double windows in sideby-side relation a vertical member 25 (Figure 9) replaces the member 25 and the structure above described is duplicated at the other side of member 25 and when a plurality of superposed single or double windows are desired a horizontal member 73 (Figure l0) is secured between each vertically adjacent duplicate pair of the openings 21 and 21a.

It should be understood that the herein shown and described forms of my window are intended to exemplify the principles of my invention and that various modications and rearrangements of its component parts may be made within the scope of the appended claims.
